    Abstract: Disclosed is a method of providing potable water that includes providing a filter, passing water through the filter, and removing bacteria and viruses from the water with the filter. The filter comprises a housing having an inlet and an outlet and a filter material disposed within the housing, the filter material formed at least in part from a plurality of filter particles consisting of mesoporous activated carbon. A sum of mesopore and macropore volumes of the filter particles may be between about 0.2 mL/g and about 2 mL/g, wherein mesopore means an intra-particle pore having a diameter between 2 nm and 50 nm, and macropore means an intra-particle pore having a diameter greater than 50 nm, a total pore volume of the filter particles is greater than about 0.4 mL/g and less than about 3 mL/g, and a ratio of the sum of the mesopore and macropore volumes to the total pore volume of the filter particles is greater than about 0.3. The filter removes bacteria and viruses from the water at a level of Filter Bacteria Log Removal of greater than about 2 logs and a Filter Viruses Log Removal of greater than about 1 log.

    Abstract: Compounds and methods for inactivating pathogens in materials are described, including compositions and methods for inactivating pathogens in biological materials such as red blood cell preparations and plasma. The compounds and methods may be used to treat materials intended for in vitro or in vivo use, such as clinical testing or transfusion. The compounds are designed to specifically bind to and react with nucleic acid, and then to degrade to form breakdown products. The degradation reaction is preferably slower than the reaction with nucleic acid.

    Abstract: An improved inclusive method for purifying a polar solvent such as water includes the re-suspension of finely divided layered materials within which contaminants have been captured, wherein the re-suspension is in a solvent selected primarily on the basis of its ability to re-suspend the finely divided layered materials and/or for its effect on the included contaminant material, and within which additional materials may or may not be intentionally dissolved, mixed, or suspended, in order to recover and reuse the finely divided layered material and/or to selectively recover a specific included contaminant or several specific included contaminants in series. The process is useful in the rapid and efficient recovery of the finely divided layered materials, and in the removal of suspended particles, dissolved materials, immiscible liquids, and living organisms from the polar solvent.
